Time to take a deeper look at this upgrade of Pyton to Python 3 and how to solve the problems that come with it.

Python 3

Historically MacOS came preinstalled with Python 2, however starting with macOS Catalina 10.15 (released in October 2019) this is no longer the case. And since Python 2 will no longer be officially supported as of January 1, 2020, you should really use Python 3 instead.

There are multiple ways to install Python 3 on a MacOS computer. The official Python website even recommends downloading it directly, however this approach can cause confusion around PATH variables, updates, and uninstalls. A better approach, in my opinion, is to instead use the popular package manager Homebrew which automates updates and juggling multiple versions of Python on a computer.

Check Python version

Link to Installing the latest version of Python on Mac OS Catalina and overriding the old default pre-installed version podcast on anchorfm; I finally did it. I successfully installed Python version 3.7.7 via Homebrew on my Mac laptop with OS Catalina installed. For those of you that still might be trying to figure out how to do this, I will. Python is a popular programming language that is widely used by beginners and longtime developers alike. Modern Mac OS versions come with Python 2.7.x installed (or Python 2.6.1 if an older Mac OS X version), but many Python users may need to update Python in Mac OS to a newer version like Python 3.8.x or newer. Mar 11, 2020 The deprecated 64-bit/32-bit installer variant for macOS 10.6 (Snow Leopard) is no longer provided. As of 3.7.7, macOS installer packages are now compatible with the full Gatekeeper notarization requirements of macOS 10.15 Catalina including code signing.

Before we start, make sure Python 3 isn’t already installed on your computer. Open the Terminal app. Click the Finder icon in your dock. Click Go. Click Utilities. Double-click Terminal.

Then type the command

followed by the Enter key to see the currently installed version of Python.
